Plum have recently collaborated with Huawei in undertaking a number of studies intended to clarify options for spectrum sharing in C-band. The report linked here addresses issues relating to the co-existence of LTE services and satellite downlinks in the same, or adjacent, spectrum. The report describes realistic field trials which illustrate the potential for geographical[…]

Plum has provided expert technical support to ComReg in relation to the future licensing and use of the 3.6 GHz band (3400 – 3800 MHz) in Ireland, following the expiry of existing rights of use for fixed wireless access local area (FWALA) licences in 2017. This included advising on the appropriate technical and other conditions[…]

We undertook a number of modelling studies for Ofcom in 2014-2015, to inform their policy on technical conditions relating to the release of 700 MHz broadcast spectrum for mobile use. The most likely band-plan involved the user equipment (UE) handsets transmitting at frequencies immediately above the remaining broadcast allocation, with base stations assigned spectrum higher[…]
